Its sounds minor, but it winds up being a huge annoyance bordering on a safety issue.

When I was shopping for my next car, I paid particular attention to this issue which was one reason I chose the A6 over a 535. I find there to be no throttle tip-in lag with my Audi. Furthermore, if I drop the gear selector into Sport mode, it is even more responsive.
